My invention relates to a weather strip construction and has as one ofthe principal objects thereof the provision of. a construction or deviceof the above described character for effectively sealing window sasheswithin window frames to preclude the passage of air currents through theclearance space therebetween.

Another object of my invention is to provide a device of the abovedescribed characterwhich is simple in construction, durable in use,efficient in operation and economical in manufacture.

Other objects and advantages will be apparent from the followingdescription, appended claims and annexed drawings.

Referring to the drawings wherein like reference characters designatelike parts throughout ranged therein, the latter being partiallyillustrated in section.

Figure 2 is a sectional view 2-2 of Figure 1.

Figure 3 is a sectional view taken on the. line 33 of Figure 1.

Figure 4 is a fragmentary perspective view of a lower corner of a windowsash illustrating my invention as applied thereto.

Figure 5 is a detail perspective view of one side of a window sashandillustrating my invention as applied thereto and in disassembledrelation.

In practicing my invention, as illustrated in the drawings, I provide awindow frame 5 in which are slidably mounted upper and lower sashes 6and I respectively. The frame is fashioned with side, top and bottomframe-pieces or members 8, 9 and H) respectively which are provided withtaken on the line grooves or channels accommodating the sash rails'ofthe sashes. The foregoing is descriptive of a window frame and sashes ofan ordinary construction and forms no part of the present invention perse.

The side end faces of the sashes have attached thereto elongated stripsor members H fashioned between their sides with inwardly extending ribsI2 disposed within grooves I3 formed in the respective rails. The ribsl2 are fashioned with lengthwise extending grooves or channels l4 andslidably receive therein ribs I5 formed on adjacently arranged elongatedcompanion members l6. s

The companion members It are provided with side sections bent uponthemselves and which terminate in right angularly arranged portionsAmsey mit ens, o'r lf v I Application AugustZl', 19s9',ser a1No.291,256}

ends of the members iii are fashioned with right angularly disposedflanges overlying and underlying the upper and lower rails of the sasheswith constituting the ribs If). The upper and lower the upper flangesconnected thereto by means of screws I! extending through elongatedslots in said upper flanges whereby to permit lateral movement of themembers I8 with respect to the members H. The outer faces l8 of themembers it; are adapted to slidably engage the faces of the sideframe-pieces 8 within channel as clearly illustrated in Figure 3 of thedrawings. Interposed between the members II and I6 and between the ribs|5 are elongated resilient strips or elements l9, one end of each beingconnected to the adjacent end of a respective member H by means of anail or the like 20. The elements l9 are transversely corrugated andcoact with members H and IE to maintain the members ll spaced withrespect to the adjacent members It and to effect engagement of the facesI8 with the faces of the side frame-pieces and thereby effect a sealbetween the side sash rails and the side frame-pieces 8.

The upper and lower sash railsof the upper and lower sashes respectivelyare recessed and each accommodates therein an elongated member 2| formedwith a lengthwise extending and centrally disposed arcuate-shaped groove22 disposed in a channel 23 formed in the respective rail. Adjacentthemembers 2| the top and bottom frame members 9 and I0 have attachedthereto by means of nails 24 or the like elongated companion members 25each fashioned with a lengthwise extending arcuate-shaped groove 26defining an arcuate-shaped rib 21 disposed within the groove 22-andcoacting with the wall of the latter to effect a seal between themembers. Obviously, when the sashes are operated to closed position, asillustrated in Figure 1, the rib 21 seats within the groove 22 andeffects a seal between the members, thereby precluding the admittance ofair between the sashes and window frame.

From the foregoing it will be apparent that I have provided a simple andefiicient device capable of being attached to window constructionswithout materially modifying the latter and which serves as an effectivemeans for precluding the passage of air currents between the sashes andframe-pieces when the sashes are in closed position.

It is obvious that the invention is not confined to the herein describeduse therefor as it may be utilized for any purpose to which it isadaptable. It is therefore to be understood that the invention is notlimited to the specific construction as illustrated and described, asthe same is only 11- lustrative of the principles of operation, whichare capable of extended application in advance forms, and that theinvention comprehends all construction within the scope of the appendedclaims.

What I claim is:

1. A weather strip construction, comprising an elongated member securedto the side edge of a sash and provided with two spaced longitudinallyextending ribs. formed with grooves opening outwardly and enteringgrooves in the sash, a second elongated member having laterally turnedends extending over the upper and lower ends of the sash, ribs carriedby the said last mentioned ing grooves in the first mentioned member,and an elongated corrugated spring secured to the first mentioned memberbetween the grooves and 16 member and entering the longitudinallyextendadapted to normally force the second mentioned member outwardly 2.A weather strip construction, comprising an elongated member secured tothe side edges of a sash and provided with two spaced longitudinallyextending ribs formed with grooves opening outwardly and enteringgrooves in the sash, a second elongated member having laterally turnedends extending over the upper and lower ends of the sash and one of saidlaterally turned ends having a slot receiving securing means carried bythe sash, ribs carried by said last mentioned member and entering thelongitudinally extending grooves in the first mentioned member, and anelongated corrugated spring secured at one end to the first mentionedmember between the grooves and adapted to normally force the sec- AMSEYCRILL.
